我国富煤少油的能源结构决定了煤化工产业的重要战略意义。“十二五”时期,在石油需求快速攀升和油价高企的背景下,我国以石油替代产品为主要方向的现代煤化工得到发展。随着一批示范工程的建成投产,我国煤化工产业步入产业化轨道,规模快速增长;技术创新取得重大突破,攻克了大型先进煤气化、煤液化及煤制烯烃、煤制乙二醇等一大批技术难题,开发了一大批大 The energy structure of China’s coal-less oil determines the important strategic significance of the coal chemical industry. In the “Twelfth Five-Year Plan” period, with the rapid rise of oil demand and the high oil price, the development of modern coal chemical industry in our country with petroleum substitute products as the main direction has been developed. As a number of demonstration projects were completed and put into production, China’s coal chemical industry entered a track of industrialization with a rapid growth in scale. A major breakthrough was made in technological innovation, capturing large-scale advanced coal gasification, coal liquefaction and coal-to-olefin and coal-to-ethylene glycol A large number of technical problems, the development of a large number of large
